I think it is going to be pro-humanity from the standpoint that humanity is just much more interesting than not-humanity.
This is not obvious, to say the least. In fact, I think this is unlikely. Non-humanity might very well be more interesting to non-human minds. E.g., if there is a maximally curious AI, it might be much more interested in tiling the surface of Earth with its conspecifics and marvelling at the complexity and interestingness of the emerging society of AIs, compared to which the humanity may appear to be utterly boring.
